Greetings.
I have two drivers, respectively based on the NetVmini and Passthru DDK
samples. On two of our Windows 2000 test machines I am experiencing some
peculiar behaviour after installing the drivers and rebooting:
The NetVmini driver's Passthru binding shows up in the device manager with
an exclamation point ("the device could not be started"). This is the only
Passthru binding that is not behaving properly.
I set SoftIce to launch at boot and looked at the trace messages I was
getting:
- ProtocolPnpEvent (NetEventsBindComplete)
- ProtocolBindAdapter
- ProtocolOpenAdapterComplete (adapter 1)
- ProtocolBindAdapter
- ProtocolOpenAdapterComplete (adapter 2)
- ProtocolBindAdapter
- ProtocolOpenAdapterComplete (adapter 3)
- ProtocolBindAdapter
- ProtocolOpenAdapterComplete (adapter 4)
- MiniportInitialize (adapter 4)
- MiniportHalt (adapter 4)
(...)
Note that MiniportInitialize successfully completes on adapter 4, as do all
the previous steps. Any ideas? This happens every single time on those
machines and it seems it's happened (rarely) on some machines I do not have
access to. Could it be a timing/sequence issue during the Windows 2000 boot
process? Also, both of my drivers are unsigned but the warning dialogs were
dismissed as usual during install.
